Description

The invention relates to a wing-stabilized balancing projectile with a penetrator and a tail unit.

Such a floor is for example from DE 30 38 087 A1 known. This is the back part of the Penetra tors trained as a carrier for the tail unit. The wings of the The tail unit is attached to a sleeve-shaped tail unit arranges, the inside diameter of the outside diameter of the rear part of the penetrator is adapted. For befe The tail is attached to the penetrator side part of the penetrator and the sleeve-shaped area of the tail unit over the circumference by soldering or gluing connected with each other.

Such known balancing bullets have the disadvantage that that they are relatively expensive to manufacture because z. B. hard solder a defined gap between the carrier of the lead factory and the inner wall of the tail unit must be present, what a corresponding accurate positioning of the two parts makes necessary. There is also a welding of the parts practically impossible over the scope. It is also at  Connections in the circumferential direction difficult, the connection subsequently on their Goodness to check out.

From DE 38 43 796 A1 a wing-stabilized balancing projectile is known in which the tail unit and the penetrator are connected by a screw connection are connected. This balancing projectile also has the disadvantage that its Manufacturing is relatively expensive because both with a separate intermediate socket External thread soldered onto the cone-shaped penetrator tail as a thread must also be introduced into the sleeve-shaped tail unit.

From US 473 086 it is known to use a tracer set Tracer carrying housing and a tail unit over a sleeve with the Connect the penetrator through a laser welding process. To do this, it is necessary the housing over a first paragraph of the penetrator and the sleeve over the Housing and slide over a second paragraph of the penetrator and in this Position in the axial direction difficult to fix by the welding process.

DE 30 09 775 A1 discloses a and can be pushed onto a penetrator tail Tail wing carrying sleeve, which, however, to avoid a bullet twist in Is arranged rotatably on the penetrator tail. A rigid one Fastening of the empennage wings on the penetrator is not provided here.

The present invention has for its object a wing-stabilized Specify the type mentioned, in which the tail on simple and is inexpensive to attach to the penetrator.

This object is achieved by the features of claim 1. More beneficial Embodiments of the invention disclose the subclaims.  

Essentially, the invention is based on the idea that the tail unit does not have to attach the perimeter to the penetrator, but an axial attachment provided. This is achieved in that the back as the carrier of the Tail unit serving part of the penetrator has a smaller diameter than the penetrator area adjoining at the front, such that in A stepped transition area between the two diameter areas Diameter jump results and that the tail unit on its front face in Area of diameter jump welded, soldered or to the penetrator is glued.  

Alternatively, the tail can also be attached via a tail ordered counter nut, which the tail unit against the front Diameter jump of the penetrator presses with the penetrator get connected.

Due to the axial fastening, both the axial forces in the event of acceleration as well as the forces in the circumferential direction transmitted during the flight phase.

The proposed axial connection has the following additional advantages over connections in the circumferential direction:

• - The tail can easily z. B. by rubbing welding or capacitor discharge welding on the Penetrator can be attached.
• - An axis positioning of the tail unit to the penetrator is possible with simple round fits.
• - In the case of brazing is an easy one Positioning of the tail unit to the defined Column setting possible.
• - The two parts can in terms of their axis parallels lity can be precisely set in a simple manner.
• - The welded, soldered or adhesive connections are very good exactly verifiable.
• - The axial connection allows a very simple interior machining of the tail unit, which is particularly the case with Use of high-strength steel tail units with an essential simplification of production is connected.

The empennage is with large transverse loads, such as. B. at the finish on an inclined plate, easily detachable. A wiping of the tail unit as a whole would

• - increase the effective endballistic length of the penetrator or
• - constructive options for additional functional elements such as B. a fire in KE ammunition enable.

Further details and advantages of the invention result from the following exemplary embodiments explained with reference to figures. It demonstrate:

Fig. 1 shows the rear-end portion of a kinetic energy projectile according to the invention, in which the tail is soldered to the penetrator;

Fig. 2 is an enlarged view of the area designated by II in Fig. 1 and

Fig. 3 shows the rear area of a further embodiment example of the balancing bullet according to the invention, in which the tail unit is attached to the penetrator via a lock nut.

In Fig. 1, 1 denotes the rear area of a wing-stabilized balancing bullet, which comprises a penetrator 2 and a tail unit 3 made of steel. The rear part 4 of the penetrator 2 is designed as a carrier for the tail unit 3 and has a smaller outer diameter 5 than the penetrator region 6 adjoining on the front, in such a way that a stepped diameter increase 7 results in the transition region.

The empennage 3 consists of a sleeve-shaped empennage body 8 , on which a plurality of wings 9 are arranged on the circumference. The inner diameter 10 of the sleeve-shaped tail unit 8 is slightly smaller than the outer diameter 5 of the rear part 4 of the penetrator, so that the latter can be inserted into the tail unit almost without play to connect the two parts.

The empennage 3 is, according to the invention, soldered to its front end side 11 in the area of the diameter jump 7 with the penetrator 2 ( FIG. 2). For this purpose, the penetrator 2 and the tail unit 8 are positioned before the soldering process in such a way that a gap 12 remains between the front side 11 of the tail unit and the jump in diameter 7 .

Fig. 3 shows the rear portion of a kinetic energy projectile 1 'again, in which the penetrator 2' is attached to the tail 3 'via a lock nut 13. For this purpose, the back part 4 'of the penetrator has a thread 14 so that when the lock nut 13 is screwed on, the tail unit 3 ' is pressed against the jump in diameter of the penetrator 2 '.

In the illustrated embodiment, the lock nut 13 also serves as a screw plug for a in the rear part 4 'of the penetrator 2 ' arranged lighting track 15th

The invention is of course not based on the above described embodiment limited. So must for Case that the tail in the area of the diameter jump of the Penetrators welded, soldered or glued, the Tail body not necessarily completely formed as a sleeve det, but it can (depending on the desired Penetra gate length) are sufficient if it is only on the Penetra gate facing side in a partial area sleeve-shaped is formed.
